You can make this recipe your own, and yes if you use dried black beans, you must soak them at least overnight, and I usually soak them, and drain, and put fresh water on them to soak longer. I read one time it makes them softer, and if you soak for a full 24 hours, they are also easier to digest. One more thing, if you heat your water to boiling, then soak them for 8-14 hours, it is said to speed up the cooking process. Enjoy and Happy Crocking.
